Subaddresses are programmable through the I 2 C-bus. Default power-up values are E2h,
E4h, E8h, and the device(s) will not acknowledge these addresses right after power-up
(the corresponding SUBx bit in MODE1 register is equal to 0).
Once subaddresses have been programmed to their right values, SUBx bits need to be
set to logic 1 in order to have the device acknowledging these addresses (MODE1
register).
Only the 7 MSBs representing the I 2 C-bus subaddress are valid. The LSB in SUBADRx
register is a read-only bit (0).
When SUBx is set to logic 1, the corresponding I 2 C-bus subaddress can be used during
either an I 2 C-bus read or write sequence.

The LED All Call I 2 C-bus address allows all the PCA9624s on the bus to be programmed
at the same time (ALLCALL bit in register MODE1 must be equal to 1 (power-up default
state)). This address is programmable through the I 2 C-bus and can be used during either
an I 2 C-bus read or write sequence. The register address can also be programmed as a
Sub Call.
Only the 7 MSBs representing the All Call I 2 C-bus address are valid. The LSB in
ALLCALLADR register is a read-only bit (0).
If ALLCALL bit = 0, the device does not acknowledge the address programmed in register
ALLCALLADR.
